“Whenever somebody asks you to do something a long time from now, change the framing and say, ‘What if it was tomorrow? Would you want to do this or not?’ Almost invariably, the answer is, ‘No, I definitely don’t want to do this tomorrow.’ And then you should answer based on that.”

— Luis von Ahn

I do my best with nutrient-dense meals, of course, but AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. 

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and five free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.

MORE GUEST QUOTES FROM THE INTERVIEW

“Something like 97 percent of our active users use Duolingo for free. Still, we make more money than all other education apps. We’re very proud of that.”
— Luis von Ahn

“If you’re not brushing with an electric toothbrush, you’re doing it wrong.”
— Luis von Ahn

“The attitude of just finding a way to become useful gets you a lot farther.”
— Luis von Ahn

“Hopefully, most people have seen the Duolingo owl. It’s our mascot. First of all, it’s an owl because in most Western countries, owls represent knowledge. Turns out this is just not true at all in Asia. Now that we’ve been expanding to Asia, people ask us, ‘Why the hell are you using an owl? Owls are just vicious animals.’”
